My mother used to sing this song to us when we were young.

A little girl and a little boy
In an ecstasy of bliss
Said the little boy to the little girl
'Pray give me just one kiss'
The girl drew back in great surprise
"Your'e a stranger, sir', said she
But I will give you just one kiss -
When the apples grow on the Lilac tree.

The boy was very sad at heart
She was the only one
The girl was quite remorseful
At the terrible wrong she had done
So bright abd early on the very next morn
He was quite surprised to se
His little sweetheart
Standing in the garden
Tying apples on the Lilac tree.
